TO ALL WHOM Il MAY CONCER:

Be it known that I, GEORGE W. (lAItPEh'DlEIt,-0` Jarvisu-De 'Kalb county, State gf Indiana, have invented certain newfand useful Improvements in Gombinerl Weather-Strip and-Alarm for Doors; and 4do hereby` declare that'the following is a full, clear, and exact description thereof, reference being-had tothe ucco1npany ing drawings, and to the letters of reference marked thereon, making a part of this specification.

In the annexed drawings, A represents the door, which is of any ordinary description, and attached to the frame Connected to `the lower `edge of thel door isa. metal plate, C, which is made to project beneath the lower edge of the door, in the usual manner. The sill is rabbeted and providedl withl e strip of'metahgfrunning its entire length, `so when'thedooris closed the plate C falls nf its own iveightand lies outsideofl thestrip g to prevent the ingress of water, dirt, &c. The out-er lower edge of the door is slightly cut, wherein is pivotod an eccentric-plate, D, which is shielded h'y a plate, a, on the edge of the door. The plate D has a. cam formed on its forward end, and extends to the front as well as to the rear ot"v the door. Connected to the rear .of this vplate D is a rod, E, which extendsl up the inside of the door, and is attached'tothe end of c. nietal plate, F.

pivoted (in its centre) to the door. G represents a cam pivoted to the vdoor near the plate F, and which said cam has two lugs on its inner face, :ttopposite sides, and is provided with a. clapper, .Ipconnected to it by means of an extending-rod. This clapper is so placed as to lie directlybeneath a bell, H, of any suitable construction, placed on the door. Krepresentsafsmall spring, wllich'is'secured to the door, and having one end lie' against one of the lugsmon the caxn Gr, v i

It will be seen' that my invention is'intended for the double purpose of' preventing lthe water, cold, dirt, Src.,

from entering the house, and at the same time to alarm the inmates when any one enters. When the door is closed, the edge of the frame keeps the outer point of the plate D down close tothe edge of the door, and as. the door is opened the metal plate g forces the cam ofthe plate D upwards in the `keeper o, thus causing the rod E to be drown', down, bringing down with it the plate F, which, catching under the lug as, in the cam Cr,

draws lsaid cam partially around-'depressing the spring, and rings the bell bythe point of the plete F sliding otf of its lug.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is i The platesI C;` and .,q, carn D,vrod E, plate F, cam G, spring K, chipper J, and bell H, all constructed,

arranged, andvoperating in the manner described, whereby an alnrxn is given bythe weather-strip, as set forth.`
